Duration of the Japanese 'sokuon' and 'haneruon' in Korean and Japanese speakers' production

The aim of this paper is to measure the duration of Japanese 'sokuon' [t/k] and 'haneruon' [m/n] produced by Korean and Japanese native speakers. It was shown that in the case of Korean speakers, the duration of geminate of 'sokuon' was 1.5 times longer than that of a single consonant, whereas in the case of Japanese speakers, it was 2 times longer. The difference between Korean and Japanese prosodic structures appears to affect the perception and acquisition of a foreign rhythmic patternm non-existent in the speaker's native tongue. The duration of geminate of [s] was 2 times as long as a single consonant in both Korean and Japanese speakers' production. On the average, the duration of Japanese 'sokuon' [t/k/s] was 1.7 times longer than that of a single consonant in Korean speakers' pronunciation, whereas 2 times longer in Japanese speakers' pronunciation. The production of 'haneruon' by either Korean or Japanese speakers yielded a similar result to 'sokoun': 1) geminates lasted longer than a single consonant; 2) single [m] is longer than single [n]: 3) geminate of [n] is 3 times as long as single [n], whereas geminate of [m] is 2 times as long as single [m].
